Title: 자전거용 상하왕복작동식 페달장치
Filed: 1998-08-28
Abstract: 1. 청구범위에 기재된 발명(고안)이 속한 기술분야 
     자전거는 인간이 발명한 대단히 귀중한 문명의 이기들중 하나로 근육의 힘외에 별도의 에너지가 필요 없으며 장거리를 빠르고 편리하게 이동 할 수 있는 유익한 장치이다. 
     본 고안에서는 인간의 다리 힘을 회전운동으로 바꾸어 바퀴에 전달하는 과정에 있어서 문제점을 찾고 그것을 해결하여 새로운 장치를 개발하는 과정을 다루었다. 
     2. 발명(고안)이 해결하려고 하는 기술적 과제 
     페달은 현재와 같이 반드시 360도를 회전 시켜야만 동력전달이 되는가?. 
     360도 회전중 체중이 실리는 하향운동 방향인 왼발 120도, 오른발 120도 정도 외에는 왼발 60도, 오른발 60도 정도는 발이 뒤로 미는 아주 미약한 힘밖에 바퀴에 전달되지않는 비효율적인 면이 있다.    또한, 오른쪽 페달을 뒤로 밀어 왼쪽 페달이 발로 밟을수 있는 위치까지 갈 수 있게 하지 않으면 안되기 때문에 비효율 구간 60도는 동력의 효과적인 전달이 되지않는 비연속적 구간이다.    따라서, 이 두가지 문제점만 해결한다면 훨씬 새로운 자전거가 될 수 있으리라 생각한다. 
     3. 발명(고안)의 해결방법의 요지 
     발로 페달을 밟는 과정인 하향운동만 반복될 수 있게 한다. 
     그러기 위해서는 현재의 페달장치처럼 좌우 페달이 동일축에 고정된 상태로서는 불가능하므로 축을 중간에서 분리되게 하되 중심은 어긋나지 않도록 할 필요가 있었으며, 또한 발을 놨을때 원위치로 페달이 복귀하게 하기위해 각각의 페달축내에 복귀스프링을 장치 하였고, 페달이 유효범위 내에서만 움직이게 하기위해 STOPPER를 장치 하였다 
     4. 발명(고안)의 중요한 용도 
     최소한의 에너지로 보다 빠르고, 편하고, 효율적으로 활동하고자 하는 것은 인간의 모든 발명품이나 과학 기구가 추구하는 기본이라 할 수 있다.    자전거는 오랫동안 사람들에게 애용 되어온 수송수단중의 하나로 본 고안의 페달장치를 적용할 경우 좀더 적은힘으로, 좀더 빠르게, 좀더 쉽고 편하게 자전거를 탈 수 있을 것이다.

Title: 사이드라이트형 면광원장치 및 액정디스플레이
IPC: G02B5/00
Filed: 1998-11-04
Abstract: 액정디스플레이는 액정패널의 백라이팅을 위한 사이드라이트형 면광원장치를 포함한다.    일차광원은 도광판으로 광을 공급한다.    출사면으로부터의 광은 프리즘시트를 거쳐 편광분리소자로 입사한다.    편광분리소자의 투과편광면(M12)과 동방향의 편광성분은 액정표시패널로 공급된다.    편광분리소자에서 반사된 복귀광은 도광판의 배면상의 볼록부열에서 내부반사되며, 편광변환된 리사이클광이 도광판으로부터 재출사된다.    리사이클광은 편광분리소자의 투과편광면(M12)과 동방향의 편광성분이 풍부한 상태에서 편광분리소자로 재입사한다.    도광판의 배면상의 볼록부의 연장방향(제1잠재방향)은 도광판의 입사면과 거의 수직이고, 편광분리소자의 투과편광면(M12), 반사편광면(M2) 모두 비스듬하게 교차한다.    프리즘시트의 내측면상의 볼록부의 연장방향(제2잠재방향)은 도광판의 입사면과 거의 평행하다.    편광분리소자와 프리즘시트는 일체화되어도 좋다.
